Still, I'm looking for every friendly piece of advice! :)
Frustration often leads to mistakes. These games are about patterns, familiarity and breaking away from your mistakes/bad habits. Trying to get greedy hits in for example is extremely common. Spamming attacks are not always inappropriate, you need to learn when to do it and when not to do it. Sometimes the game will bully you. There is no way to know of some of the traps or dangers but you can learn from them.
Your dodge is exceptional. It has some invincibility frames in the animation and you can actually use this to dodge
through some attacks. Incredibly handle for slower but powerful attacks with no follow ups as once you have the timing down you can evade through it and be in position to retaliate immediately.
"Farming blood vials" aka farming healing potions is a common complaint. My method of fighting against this is
-spending excess blood (from leveling) on vials before leaving the dream area.
-Admit that sometimes I have played extremely poorly and simply reset the area rather than spend my healing items. It lets me practice with the enemies again, conserve healing items and earn more blood. If I'm using all my healing items just to get through an area then I feel like I'm doing something wrong.
-Some enemies are tougher than others and might not really be worth fighting.
Shoot small dogs to stop them and allow for openings. Won't work on large wolf like creatures.
The parry is risky but rewarding. It will also make some fights much easier if you learn it.
Edit.
So I totally didn't see there was a page 2. Bad form, mod shame commence!
Another question: I've reached an area past the two hunters near the cathedral and entered a big hall where I was instantly killed by some sort of Ghost that picked me up into the air. WTF?! Can I do anything about it or should I return later.
If you possess certain items, this thing will take you to places. One of the items you get from the Hunter's Dream, it is laying on the ground but appears after a certain boss. This will take you to the DLC area which I do not recommend until later in the game.
